8-11 Manually Releasing the Brake
To manually release the brake with the power off, operate the brake release mechanism as shown below.
■
FB Brakes (excluding FB-20, FB-30)
(FB-01A1 – FB-05A1 are options)
(1) First remove the brake release bolts from the 2 opposing angles and remove the release prevention spacers. Reinsert the bolts and
rotate with a hexagonal wrench to release the brake. Be careful not to over rotate the brake release bolts. (Rotate the brake release
bolts while checking to see if the brake is released. (See Figures 8-36, 8-37)
(2) After releasing the brake, to return it to its original condition, for safety, return the manual release prevention spacers that were
removed in (1) to their original positions. (See Figure 8-37)
(3) This table show brake release bolt sizes.

FB-20, FB-30
(1) In the case of outdoor types, remove the lid on the window part of the the outdoor cover [33]. Remove the grommet [28] (indoor
type), remove the brake release bolt [2] using a hexagonal wrench (for an M8 hole bolt), and remove the rubber gasket [3] and
the manual release prevention spacer [4]. The brake will release when you again rotate the bolt using the hexagonal wrench. Be
careful not to over rotate the brake release bolt. (Rotate the brake release bolt [2] while checking to see if the brake is released.) (See
Figure 8-38)
(2) After releasing the brake, to return it to its original condition, for safety, return the manual release prevention spacer and the rubber
gasket [3] that were removed in (1) to their original positions, and firmly tighten the brake release bolt [2]. (See Figure 8-39)
Next re-attach the grommet [28] (indoor type) in its original state. In the case of outdoor types, attach the lid on the window part
of the the outdoor cover [33] as it was before.
-Note that if the rubber gasket [3] and the seal washer [5] for the brake release bolt [2] unit are not attached when returning to
the original state, dust-proofing and waterproofing capabilities will be lost.
Also, firmly tighten the brake release bolt [2]. Otherwise waterproofing capability may be lost.
Also make certain to return the grommet [28] (indoor type) or outdoor cover [33] window lid (outdoor type) to their original
states.
-If the machine is operated when the brake release bolt has not been returned to its original position, in the worst case it is
possible that the manual release would function before maximum gap is obtained, and the brake would cease to function.
Therefore, make certain to always operate with the manual release prevention spacer attached.
